Hi list... my bad, too much time without using mailing lists, I missed

I'm forwarding my replies to David Klann, who thankfully replied me, so

Hi. Thank you for your help.
I don't know enough about the rivendell ecosystem to guess whether its
system-side issue (permissions a good candidate) or some Database issue
(bug)
System side, with the exception pf the pypad daemon, it looks to me
everything is 'root' driven:
root@rd-terminal-alex:~# ps aux | grep sbin/rd
root 489 3.9 0.7 211456 27884 ? Ssl 18:07 2:32
/usr/sbin/rdservice
root 586 4.9 2.7 211824 103120 ? SL 18:07 3:11
/usr/sbin/rdcatchd
root 587 0.0 0.6 136524 24948 ? S 18:07 0:00
/usr/sbin/rdpadd
pypad 588 4.1 0.7 211196 26376 ? S 18:07 2:41
/usr/sbin/rdpadengined
root 589 4.9 0.9 218348 36488 ? S 18:07 3:11
/usr/sbin/rdvairplayd
root 693 0.0 0.0 6208 888 pts/0 S+ 19:12 0:00 grep
sbin/rd
Anyways, I checked the existence of the ttyS0 device (although I don't
understand why is it checked for a Sound Card based GPIO) and dialout perms:
root@rd-terminal-alex:~# ls -l /dev/ttyS0
crw-rw---- 1 root dialout 4, 64 May 5 18:07 /dev/ttyS0
root@rd-terminal-alex:~# cat /etc/group | grep dialout
dialout:x:20:operador,rivendell
Both look good .... in the meantime, I investigated a little the source
code and checked the Database table:
MariaDB [Rivendell]> select * FROM TTYS;
+----+---------+--------+------------------+------------+-----------+-----------+-----------+--------+-------------+
| ID | PORT_ID | ACTIVE | STATION_NAME | PORT | BAUD_RATE |
DATA_BITS | STOP_BITS | PARITY | TERMINATION |
+----+---------+--------+------------------+------------+-----------+-----------+-----------+--------+-------------+
| 1 | 0 | Y | rd-terminal-alex | /dev/ttyS0 | 115200
| 8 | 1 | 0 | 0 |
| 4 | 1 | N | rd-terminal-alex | /dev/ttyS1 | 9600 |
8 | 1 | 0 | 0 |
| 7 | 2 | N | rd-terminal-alex | /dev/ttyS2 | 9600 |
8 | 1 | 0 | 0 |
| 10 | 3 | N | rd-terminal-alex | /dev/ttyS3 | 9600 |
8 | 1 | 0 | 0 |
| 13 | 4 | N | rd-terminal-alex | | 9600 |
8 | 1 | 0 | 0 |
+----+---------+--------+------------------+------------+-----------+-----------+-----------+--------+-------------+
6 rows in set (0.000 sec)
So the TTYs are there... and, if I tick the checkbox to enable the
serial port, the ACTIVE field switches Y/N.
Apparently the problem comes as rdedit_matrix.cpp seems to call Active()
function of rdtty.cpp , I'm not sure about this...I digged just a little
bit more there and ended at GetStringValue(const QString &field)
function, which queries de database like this:
MariaDB [Rivendell]> select ACTIVE from TTYS where
STATION_NAME="rd-terminal-alex"&&PORT_ID=0;
+--------+
| ACTIVE |
+--------+
| Y |
+--------+
1 row in set (0.000 sec)
If the first Active() call fails, then the QMessageBox with the "The
primary serial device is not active!" string is triggered , which I
think is what I'm seeing (not really sure, but I bet is this)... why
does Active() fails? I don't know ... hopefully I'm missing some obvious
system-side detail.
Thank you very very much for your help!
Best regards!

Looks like you subscribed correctly!
To the subject: I'm trying to setup a Local Audio Adapter GPIO in
RDAdmin.
The problem is that no matter what, I can't proceed since I got a
RDAdmin Error pop-up window stating: "The primary serial device is no
active!"
I have tried declaring /dev/ttyS0 (the PC serial port as seen in /dev)
in RDAdmin in Serial Ports just in case.
I don't understand why the form cares about serial not being
active...what am I doing wrong?
Thank you very much in advance.
My first guess is this is a permissions problem.
On my systems "ls -l /dev/ttyS0" looks like this:
crw-rw----. 1 root dialout 4, 64 Apr 9 15:54 /dev/ttyS0
And I know that neither Linux user "rd", nor "rivendell" are in the
"dialout" group. Try this:
sudo usermod -a -G dialout rd
Then log out and back in (or reboot). Please report back if this helps.
Best,
~David Klann
